Purpose The Industry 4.0 initiative – with its ultimate objective of revolutionizing the supply-chain – putted more emphasis on smart and autonomous systems, creating new opportunities to add flexibility and agility to automatic manufacturing systems. These systems are designed to free people from monotonous and repetitive tasks, enabling them to concentrate in knowledge-based jobs. One of these repetitive functions is the order-picking task which consists of collecting parts from storage (warehouse) and distributing them among the ordering stations. An order-picking system can also pick finished parts from working stations to take them to the warehouse. The purpose of this paper is to present a simplified model of a robotic order-picking system, i.e. a mobile manipulator composed by an automated guided vehicle (AGV), a collaborative robot (cobot) and a robotic hand. Design/methodology/approach Details about its implementation are also presented. The AGV is needed to safely navigate inside the factory infrastructure, namely, between the warehouse and the working stations located in the shop-floor or elsewhere. For that purpose, an ActiveONE AGV, from Active Space Automation, was selected. The collaborative robot manipulator is used to move parts from/into the mobile platform (feeding the working stations and removing parts for the warehouse). A cobot from Kassow Robots was selected (model KR 810), kindly supplied by partner companies Roboplan (Portugal) and Kassow Robotics (Denmark). An Arduino MKR1000 board was also used to interconnect the user interface, the AGV and the collaborative robot. The graphical user interface was developed in C# using the Microsoft Visual Studio 2019 IDE, taking advantage of this experience in this type of language and programming environment. Findings The resulting prototype was fully demonstrated in the partner company warehouse (Active Space Automation) and constitutes a possible order-picking solution, which is ready to be integrated into advanced solutions for the factories of the future. Originality/value A solution to fully automate the order-picking task at an industrial shop-floor was presented and fully demonstrated. The objective was to design a system that could be easy to use, to adapt to different applications and that could be a basic infrastructure for advanced order-picking systems. The system proved to work very well, executing all the features required for an order-picking system working in an Industry 4.0 scenario where humans and machines must act as co-workers. Although all the system design objectives were accomplished, there are still opportunities to improve and add features to the presented solution. In terms of improvements, a different robotic hand will be used in the final setup, depending on the type of objects that are being required to move. The amount of equipment that is located on-board of the AGV can be significantly reduced, freeing space and lowering the weight that the AGV carries. For example, the controlling computer can be substituted by a single-board-computer without any advantage. Also, the cobot should be equipped with a wrist camera to identify objects and landmark. This would allow the cobot to fully identify the position and orientation of the objects to pick and drop. The wrist camera should also use bin-picking software to fully identify the shape of the objects to pick and also their relative position (if they are randomly located in a box, for example). These features are easy to add to the developed mobile manipulator, as there are a few vision systems in the market (some that integrate with the selected cobot) that can be easily integrated in the solution. Finally, this paper reports a development effort that neglected, for practical reasons, all issues related with certification, safety, training, etc. A future follow-up paper, reporting a practical use-case implementation, will properly address those practical and operational issues.

“…A novel design for a granular capacitive moving bed bioanode was developed, where activated carbon granules circulated using a gas lift and settled through an internal discharge cell. This new reactor design was based on the continuous sand filter reactors [152], which circulate sand particles, commercially known as Dynasand by Nordic Water (Nordic Water (https://www.nordicwater.com/product/dynasand/)), in order to create a moving granular bed.…”

“…In relation to real wastewater, narrowing the width of the discharge cell increases the risk of clogging due to suspended solids [90,91]. This may be mitigated by using a washing compartment to separate suspended solids, as well as sheared off biofilm, from the water stream, as used in continuous sand filter systems [152], after which the moving bed reactor was designed [107].…”

Chapter 1 1.1. Wastewater treatment technology for removal of organic material Environmental challengeIn modern society, municipalities and industry produce significant volumes of wastewater. Globally, on average 95 m 3 wastewater is produced per capita per year, with in Europe 124 m 3 /capita/year and North America at 231 m 3 /capita/year: a global total of 380×10 9 m 3 per year (2015 data) [1]. Wastewater contains a mixture of several pollutants, such as dissolved organics, and nitrogen and phosphorus compounds, with differing effects on the environment and ecosystems. In nature, the dissolved organics are degraded by aerobic bacteria, resulting in the deoxygenation of the water. This is especially problematic for wastewater discharged into surface waters, which host important ecosystems that rely on oxygen in the water. Nitrogen and phosphorus discharge can result in eutrophication, which in turn leads to reduced biodiversity and possible toxicity due to proliferation of certain algae species [2,3]. At the end of the 19 th century, wastewater treatment -rather than disposal -became more important as these consequences became clear [4]. Wastewater treatment plants (WWTPs) were constructed, connecting in 78% of the population in the EU to primary and secondary treatment (EU-28, status in 2017) [5]. The wastewater treatment process consists of several steps, including but not limited to: primary treatment for the removal of (suspended) solids, secondary for removal of organics, and tertiary for removal of nutrients, minerals, metals, inorganics, taste, color, odor and pathogens [6]. Traditionally, aerobic treatment has been used to remove these organics, but the recovery of energy contained in the organics, has become a goal in itself: firstly, to make the WWTPs less energy intensive and more self-sustainable and secondly to export the energy for use in society. Aerobic treatment and recovery of the energy from organics in wastewater using anaerobic digestion processes and bioelectrochemical systems will be discussed in the following paragraphs [7,8]. Aerobic treatmentAerobic treatment utilizes oxygen for the oxidation of dissolved organics by aerobic bacteria in the controlled environment of WWTPs. Traditional treatment uses large ponds to flow the wastewater through. Oxygen is forced into the water stream at various points in the pools, and the required oxygen is consumed by the growing bacteria while degrading the organic material. The aerobic biomass is collectively called activated sludge. The aeration requires significant amounts of energy. In the last decade, the aeration step consumed between 0.1 and 0.6 kWh/m 3 wastewater in various WWTPs around the world, depending, among others, on climate, size, technology, and chemical oxygen demand (COD) and total nitrogen requirements of influent and effluent [7]. For typical wastewater, 0.5 kgCOD/m 3 [9], the aerobic energy costs are 0.2 to 1.2 kWh/kg COD. The growth of aerobic microorganisms results in a large volume of sludge in suspension in the wastewater stre...
